Bug ID: 28508
Summary: Assertion failed: !isa<TagDecl>(this) ||
!cast<TagDecl>(this)->isCompleteDefinition()
Product: clang
Version: 3.8
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: jt...@ca.ibm.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
This problem only happens when I try to compile the test case as a c file using
clang, if I compile it as a c++ file using clang++, there is no assertion.
Steps to reproduce on linux:
-bash-4.2$ cat r.c
int main()
{
typedef char* CHARPT;
for (struct CHARPT {int i;} a;;) {}
return 55;
}
-bash-4.2$ clang r.c
r.c:4:15: error: declaration of non-local variable in 'for' loop
for (struct CHARPT {int i;} a;;) {}
^
clang: /home/jtony/build/3_8/llvm-dev.src/tools/clang/lib/AST/DeclBase.cpp:113:
void clang::Decl::setInvalidDecl(bool): Assertion `!isa<TagDecl>(this) ||
!cast<TagDecl>(this)->isCompleteDefinition()' failed.
...
1. r.c:5:3: current parser token 'return'
2. r.c:2:1: parsing function body 'main'
3. r.c:2:1: in compound statement ('{}')
clang: error: unable to execute command: Aborted (core dumped)
clang: error: clang frontend command failed due to signal (use -v to see
invocation)
clang version 3.8.0 (tags/RELEASE_380/final)
Target: powerpc64le-unknown-linux-gnu
Thread model: posix
